Im finding this company very good
http://www.lmhsoft.com/ . None of that pay per email sent, just sign up and away you go.
My only problem with it is the direct sending. You can send on the customers server, meaning if their server is okay with sending it. Im not keen on this option as I have about a 30 % fail in sending. If you can send on your own smtp server however the delivery I have been having is excellent.
My feeling it is run by a chinese bloke as I feel they are not a big company and he is very good at follow up, and help is very quick.
You can try a trial which allows 50 emails or 100 not sure and to buy it, it is 100US dollars or the pro version is about another 100 which just allows more emails to be sent in one batch. The version I have is 2000 emails per time and at the moment as Im still trying it myself.
So I would appreciate replies and thoughts about this also.
